We introduce a compartmental model SEIAHRV (Susceptible, Exposed, Infected, Asymptomatic, Hospitalized, Recovered, Vaccinated) with age structure for the spread of the SARAS-CoV virus. In order to model current different vaccines we use compartments

We consider a modification of the well studied Hamiltonian Mean-Field model by introducing a hard-core point-like repulsive interaction and propose a numerical integration scheme to integrate numerically its dynamics. Our results show that the outcom

Ensemble inequivalence and Maxwell construction in the self-gravitating ring model

Equilibrium Statistical Mechanics is undoubtedly a cornerstone for the description of many particle systems. The common interpretation is based on ensemble theory as put forward by Gibbs, alongside the basic assumptions that different ensembles are e

Corrigendum: Quantum teleportation of thermofields (2019 Phys. Scr. 94 095102)

There was a misprint in the title of the paper: Quantum teleporation of thermofields (2019 Phys. Scr. 94, 095 102). It should be read Quantum teleportation of thermofields. The word teleportation is correct all along the manuscript, but it is misprin

Non-classical symmetries and invariant solutions of non-linear Dirac equations

Publikováno v: Communications in Nonlinear Science and Numerical Simulation. 26:201-210

We apply Lie and non-classical symmetry methods to partial differential equations in order to derive solutions of the non-linear Dirac equation corresponding to the Gross–Neveu model in d = ( 1 + 1 ) and d = ( 2 + 1 ) space–time dimensions. For e
